SOMA was working fine up until (yes, there are possible spoilers here):

Spoiler below!

picking up Catherine into the Omni-Tool and having to leave Lambda. I left Lambda and then headed over a metal tunnel like structure in the ocean overworld, got jumpscared and headed into some structure I couldn't get in to before I went into Lambda. Explored then came back out thinking it was a dead end. I stopped outside on the tunnel structure.

I saved the game at that point, since I wanted to take a break. Upon reload, I now get an error loading up the save:
